RAIL GAUGING DEVICE Filed March 26, 1928 Patented Feb. 24, 1931 UNITEDSTATES LOUIS ."B. QUAM, MARSHALL w. NORTHINGTON, AND JOHN D. sawynn, orNEAR nasrr- LAND, TEXAS RAIL-GAUGING nnvi'cn This invention relates tonew and useful improvements in rail gauging devices.

' One object of the invention is to provide a device for gauging therail of a railroad track, which may be set and operated by one man. I

A further object of the invention is to provide a rail gauging devicewhich will be complete in itself and which one man may convenientlycarry while inspecting the track. i

A still further object ofthe invention is to provide a device'forgauging rails, which may be easily and quickly placed in position andwhich may be left in place'against the rail, if necessary, until,permanent fastenings can be applied. f 3

A construction designed to carry out the invention will be hereinafterdescribed, to gether with other features of the invention.

The invention will be more readily understood from a reading of thefollowing speciing drawings, in which an example ofthe invention isshown andwherein:

Fig. 1 is a view showing a device constructed in accordance with theinvention applied to a rail and the tie supporting the same, portionsbeing shown in elevation and portions in section,

Fig. 2 is a horizontal cross-sectional view taken on the line 2-2 ofFig. 1, and

Fig. 3 is a transverse sectional view on the line 33 of Fig. 2.

In the drawings the numeral 10 designates a chair having an upstandingtransverse abutment 11 rising from the central portion of a baseplate12. The chair is prefer-ably formed of one piece and may be madefrom a strip of metal suitably bent or forged into shape; however, itmay be made in any suitable way. The abutment 11 is provided with aninclined seat 13 located between two up- .right bosses 14.

In order to fasten and quickly apply the taken 3 i chair, the plate 12isprovided with a pluralityof depending prongs or pointed studs 15 whichmay be slightly curved. The chair 5 may be placed upon thetie A and anyconfication and by reference to the accompany- I venient instrument usedfor driving the prongs 15 into said tie. The purpose of the prongs istoresist longitudinal displacement from the rail and it is obvious thatthe prongswould not need to be very long and by slightly theywill resista great strain.

The purposeof the chair is to supportone end of a 130k which comprises abarrel 16 having internal screw-threads 17 at one end for recelvlng ascrew-threadedshank 18 having ahead 19 at its outer end. A plug 20 issuitably fastenedin the oppositeend of the barrel: and carries aswivelhead 21 formed integral th6I8Wltl1.. i A cap 22 is confined on the head21 so as to form a swivel connection the shanks18.w The jack may be usedin p1acinggthe chair in position, the head 19 being employed as ahammer. I i I In uslng the device, the chair 10 is posi- 1310I1(lLSshown an the drawings and the head 19 is slidinto the seat 13 betweenthe bosses 14, the seat being just wide enough to freely receive thehead, butto prevent rotation thereof. The head 19 rests against theabutment 11. Owing to the swivel connection of the cap 22, the face 23may be placed flatagainst the web C of the rail B. This disposes thejack at an angle and throws the upper portion of the bar 25 away fromthe rail so that it may be freely swung to rotate the barrel. After thejack is in place the spikes D are pulled and thenby rotating the barrel16 the shank 18 is expelled, whereby the rail B is displaced inwardly ofthe track, as is shown in dotted lines in Fig. 1.

The workman adjusts the rail to the proper gauge and then redrives thespikes D to hold it in place. If he does not have means for drivingspikes, he can leave the device in PATENTOFFICE *urving them away fromthe rail, 1

place until the rail can be permanently secured. The entire equipment issmall and may be easily handlel and carried. ,One man 1 can readilyoperate the device and can gauge the rail to a minute degree.

' Various changes in the size and shape of the different parts, as Wellas modifications and alterations, may; be 'made Within the scopeof theappended claims.

What We claim is:

1. In a-rail gauging'device, a'ch air having 1 an inclined abutment andadapted to removably engage With a tie, and a jack having a ,heacl'atone end engaging the abutment of the chair and a swiveled cap at theother end.
